Hard to assemble glider

In a decade and a half of soaring I've somehow never ended up being involved in the assembly of a glass SH glider so could someone clarify something for me? By the sound of it the SH system uses a single pin to hold the wings together laterally and spigots extending out from each spar end that engage with fittings in the root of the opposing wing to take up the bending loads on the spars - much like a Glasflugel - but they don't include a rigging tool that draws the wings together the last couple of inches? Seems like an odd omission. I thought Grob was the only manufacturer that did something like that, though they do at least use those locking collars instead of a pin which does allow you to secure the first wing in so you don't have to worry about pushing it out when trying to slide the second wing home.
